With the rapid development of information technology, smart cities have become an important direction for the development of modern cities. In the construction of smart cities, one-network management is an important strategy for urban management. By integrating various information resources, it can achieve optimal resource allocation and rapid response to problems. Among them, video technology, as one of the key applications in the one-network management scenario, is becoming increasingly important.

1. The core role of video technology in unified network management

In the one-network management scenario, video technology mainly undertakes core tasks such as real-time monitoring, intelligent analysis, and data integration. Through high-definition cameras, sensors and other equipment, comprehensive coverage of urban public areas is achieved, and various event information is captured in real time. At the same time, combined with artificial intelligence, big data analysis and other technologies, video data is intelligently analyzed to extract valuable information and provide decision support for urban management.

2. Specific performance of video and intelligent analysis technology in one-network management

1) Video resource integration and management

In the one-network unified management system, video surveillance resources are an important foundation for building digital and visual governance. The EasyCVR video aggregation platform can achieve unified video capability management of video resources, providing functions including video surveillance live broadcast, video carousel, video recording, cloud storage, playback and retrieval, intelligent alarm, etc., to ensure the effective use of massive video data.

• Adopt direct access method to integrate public area video resources;
• Adopt visual network access method to integrate video resources of social units;
• The visual network access method is used to integrate the security alarm monitoring resources built by shops along the street, communities and residents' homes.

The EasyCVR video aggregation platform can also provide a unified video point map spatial display capability, form a complete video asset service for urban video resources, and provide a standard API interface to meet the different needs of different units for video calls.

The features of the video aggregation EasyCVR security integrated monitoring platform are as follows:

• Video aggregation management: Smart security monitoring EasyCVR video management platform can centrally access and aggregate front-end monitoring devices in a complex network environment;
• Multi-protocol access: support national standard GB/T 28181 protocol, ministry standard JT808, GA/T 1400 protocol, RTMP, RTSP/Onvif protocol, Hikvision Ehome, Hikvision SDK, Dahua SDK, Huawei SDK, Uniview SDK, LeCheng SDK, EZVIZ Cloud SDK, etc.
• 24-hour monitoring: supports 7*24 hours real-time high-definition video monitoring, can play multiple monitoring video streams at the same time, with 1, 4, 9, 16 video screens optional, and supports custom video carousel;
• Video transmission: Support H.264/H.265 video compression technology, and can transmit 720P/1080P/2K/4K high-definition video in 4G/5G/WIFI/wired and other network environments;
• Streaming media distribution: It can distribute RTMP, RTSP, HTTP-FLV, WebSocket-FLV, HLS, WebRTC, ws-fmp4, http-fmp4 and other video streams, and supports viewing on multiple terminal devices;
• Video playback and storage: Supports video recording, storage, and playback functions. You can view the on-site incident by reviewing the video recording and use the video recording as evidence to trace responsibility;
• GIS map: Based on the geographical location information of the device, visualization, spatial point layout display, and video viewing can be achieved on the map;
• System operation and maintenance management: It has management capabilities such as permission/user/role management, equipment classification and grouping management, authentication management, server clusters, operation logs, and operation and maintenance plug-ins.
• Scalability: The platform provides standard API interfaces to facilitate development and integration.

2) Visual display and monitoring

The integrated video management platform displays important data in real time through a visualization platform, and provides a picture of all information, including the number of online devices, the number of intelligent analysis devices, alarm information, etc., providing managers with an intuitive and efficient way to obtain information. It supports remote online video monitoring, achieving all-weather, all-round, and no-dead-angle real-time monitoring to ensure safe and orderly urban operations.

3) Intelligent analysis and early warning

Introducing intelligent analysis technologies, such as computer image vision analysis technology, which can separate the background and target in the video scene in real time, analyze and track the targets appearing in the camera.

Based on AI intelligent analysis software or hardware (TSINGSEE AI algorithm middleware/AI intelligent analysis gateway), a variety of intelligent detection and alarm rules can be preset. Once the target behavior violates the predefined rules, the system will automatically issue an alarm and display the alarm information through the monitoring workstation, allowing managers to respond quickly.

Specific intelligent analysis applications include automatic identification and early warning of urban management issues such as occupying the road for business, roving vendors, and out-of-store operations, realizing a full-process closed loop of perception, acceptance, transfer, disposal, and verification of early warning events.

4) Three-vehicle supervision and mobile applications

Generally speaking, the city's unified network management platform can record and display vehicle data collected by vehicle capture cameras, realize the supervision of three vehicles on the construction site (dump trucks, mixer trucks, and material transport trucks), and search and view them by license plate number, vehicle type, etc., to realize dynamic recording of vehicles.

It is necessary to provide mobile application support so that users such as street urban management law enforcement offices, venue owners, and nearby residents can view videos and video playbacks of urban management scenes in the streets under their jurisdiction anytime and anywhere, receive early warning messages, handle them in a timely manner, and support reporting of illegal activities.

5) Cloud-edge-device integration and multi-algorithm application

Through the integration of cloud, edge and end, we build a scenario algorithm center and adopt multi-algorithm fusion technology to provide intelligent analysis and judgment capabilities for the weak links of urban management, enabling one-network intelligent management. Combined with the alarm information of the alarm center, we can fully release the value of perception data and improve the level of refinement and intelligence of urban management.

3. Application cases of video technology in urban management

1) Road improvement: For problems such as illegal parking of motor vehicles, street vendors, garbage accumulation, etc., the video surveillance system is combined with intelligent analysis technology to realize automatic identification and push of illegal behaviors. This greatly reduces manpower input, improves work efficiency, and also improves the level of refinement of urban management.

2) Farmers’ market order control: In crowded places such as farmers’ markets, video technology can monitor market order in real time and promptly detect and handle all kinds of violations. This helps maintain market order and achieve safety supervision.

As the construction of smart cities is further advanced, the application of video technology in one-network unified management scenarios will become more extensive. In the future, video technology will develop in the direction of higher definition, higher intelligence, and higher integration, providing more comprehensive, efficient, and accurate support for urban management. At the same time, with the rapid development of technologies such as 5G and the Internet of Things, video technology will be deeply integrated with these technologies to jointly promote the construction and development of smart cities.
